My invention this year is going to be VERY useful!!!!!
It is called the Ultra violet jewellry range, including rings, bracelets, earrings as well as the UV drink bottle sleeve for people on the go.
The UV jewellry & drink bottle sleeve show the wearer or athlete the Ultra Violet levels while they are out and about. The clours on the indicators change according to the strength of UV.
Bright Bule=very strong UV and it is very dangerous!!
Violet =strong UV,still dangerous!!
pink =medium UV ,but be careful!!
yellow =low UV not very dangerous!!
white =very low UV not dangerous!!
Ultraviolet Rays
Most people are aware of the effects of UV through the painful condition of sunburn, but the UV spectrum has many other effects, both beneficial and damaging, on human health.
Discovery
The discovery of UV radiation was intimately associated with the observation that silver salts darken when exposed to sunlight. In 1801 the German physicist Johann Wilhelm Ritter made the hallmark observation that invisible rays just beyond the violet end of the visible spectrum were especially effective at darkening silver chloride-soaked paper.
The name means "beyond violet" (from Latin ultra, "beyond"), violet being the color of the shortest wavelengths of visible light. UV light has a shorter wavelength than that of violet light.
The sun emits ultraviolet radiation in the UVA, UVB, and UVC bands. The Earth's ozone layer blocks 97-99% of this UV radiation from penetrating through the atmosphere. 98.7% of the ultraviolet radiation that reaches the Earth's surface is UVA
Beneficial effects
Vitamin D
UVB exposure induces the production of vitamin D in the skin. The majority of positive health effects are related to this vitamin.
Harmful effects
An overexposure to UVB radiation can cause sunburn and some forms of skin cancer. In humans, prolonged exposure to solar UV radiation may result in acute and chronic health effects on the skin, eye, and immune system.
UVC rays are the highest energy, most dangerous type of ultraviolet light. Little attention has been given to UVC rays in the past since they are filtered out by the atmosphere. However, their use in equipment such as pond sterilization units may pose an exposure risk, if the lamp is switched on outside of its enclosed pond sterilization unit.
UVA, UVB and UVC can all damage collagen fibers and thereby accelerate aging of the skin. Both UVA and UVB destroy vitamin A in skin, which may cause further damage.In the past, UVA was considered less harmful, but today it is known that it can contribute to skin cancer via indirect DNA damage.

¨ John Britten (New Zealander) John Kenton Britten (1 August 1950 – 5 September 1995) was a New Zealand mechanical engineer who designed a world-record-setting motorcycle with innovative features which are still ahead of contemporary design.A dyslexic, he needed to have exam questions read to him at school and during his tertiary education, and his answers recorded by a writer, but that didn't stop him from developing into a remarkable engineer and architectural designer.
John worked on motorcycle design for some years, developing innovative methods using composite materials and performance engine designs. He created the Britten Motorcycle Company in 1992 to produce revolutionary machines to his own design made of light materials and using engines he built himself, which became famous around the world.
His Britten motorcycles won races and set numerous speed records on the international circuits, and astounded the motorcycle world in 1991 when they came a remarkable second and third against the factory machines in the Battle of the Twins at Daytona, United States Of America.
Bill Gallagher (New Zealander)
The Gallagher story started in the 1930's when Bill Gallagher senior, founder of the Gallagher Group, used his ingenuity to develop practical mechanical solutions for his underdeveloped farm.
When Joe the Horse used the Gallagher family car as a scratching post in the early 1930's, the horse could not have known what his annoying habit would lead to. It is doubtful that Bill Gallagher visualised his pioneering future when he set up the electric circuit that charged the car to break the horse's habit. Hard lesson for the horse, innovative start for Bill.
In 1937 Bill Gallagher made his first electric fence. He had read that in America they were using electrified wire to hold stock. He used mains power supply to power the fence until his circuit was deemed illegal and disconnected by authorities. Undaunted, he developed fences that were powered by batteries and Ford coils. They had their weaknesses, but it was a start.
Bill developed and experimented until, given their limitations, they performed as best they could. But by the early 1960's the battery-powered fences abilities had peaked. They only had full effect in small areas and their growth would have only been achieved through advances in technology that were not likely to occur for a while. Then, fortunately for the business of animal control, the law regarding main power supply usage was changed in 1961, and Power Fencing as the world knows it today, was legally born. ¨ Bill Hamilton (New Zealander) Sir Charles William Feilden Hamilton (26 July 1899 - 30 March 1978), commonly known as Bill Hamilton, was a New Zealander who developed the modern jetboat, and founder of what is now the world's leading water jet manufacturing company - CWF Hamilton Ltd
Hamilton never claimed to have invented the jet boat. He once said "I do not claim to have invented marine jet propulsion. The honour belongs to a gentleman named Archimedes, who lived some years ago". What he did was refine the design enough to produce the first useful modern jet boat.
In the 1950s Hamilton set out to try to build a boat that could navigate the shallow fast flowing rivers where he lived. The rivers were too shallow for propeller driven boats to navigate as the propeller would hit the river bottom.
He investigated the American Hanley Hydro-Jet, a model which drew in water and fired it out through a steerable nozzle underneath the boat. Even when further adapted it did not work well. An employee suggested to have the nozzle just above the waterline.
When he took one of his early demonstration jet boats to the US, the media scoffed when he said he planned to take it up the Colorado River (U.S.), but in 1960 a Hamilton jet became the first boat to travel up through the Grand Canyon. The critics were silenced further when the boat also went down river through the canyon.
He was born at Ashwick Station near Fairlie (South Island, New Zealand).
Hamilton survived an aeroplane accident returning to Rongotai Airport (Wellington) in poor conditions on 19 February 1937. The collision with the anemometer took the starboard wing off the Miles Falcon Six he was travelling in, and killed pilot Malcolm "Mac" McGregor.
